Just because the book "Gadfly" describes a strong soul and unyielding ideals.

Paul Korchagin once said a famous saying about life: The most precious thing for people is life. Life belongs to us only once. A person's life should be spent like this: when he looks back on the past, he will not regret for wasting his years, nor will he be ashamed for doing nothing. When he was dying, he was able to say: "My whole life and all my energy have been dedicated to the most magnificent cause in the world - the struggle for the liberation of mankind."

The Gadfly is also known as A tenacious and unyielding soul supported a broken body and fought bravely on the revolutionary road full of thorns until the last moment of life. The bumpy life journey and the twists and turns of the revolutionary road could never conquer his strong heart.

The gadfly’s unyielding strength made Paul strong!
